The original sheave and pulley mounting program developed to facilitate installation and replacement of components.
The QD (Quick Detachable) design provides for both conventional (flange outboard) and reverse (flange qd bushing china inboard) mounting configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven product are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end first. Assemble key.
3. Placement QD bushing on shaft. Tighten established screw over key “hand tight” with standard Allen wrench only. Usually do not use excessive force.
4. Slide large end of sheave or sprocket taper bore into placement over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
NOTE: Install M thru S bushings in the hub to ensure that both extra holes in the hub are located as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Do not make use of extensions on wrench handles. There should be a gap between your face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone hold and press fit.
CAUTION: THIS GAP MUST NOT BE CLOSED.
Use a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power transmission applications. Flanged quick-disconnect bushings feature a completely split style to help provide easy 
installation and disassembly. A tapered bushing with straight edges uses an internal screw to greatly help drive the bushing in to the shaft, while a split taper has a flange and an integral on the bushing to greatly help provide more drive.
QD bushings (inch and metric sizes) possess a flanged design and show a 4° taper with conventional or reverse mounting. They are stocked in popular finished bore sizes and minimal plain bore for custom reboring.
Many people refer to both types as a “taper lock” because they both utilize the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, uses a set screw to operate a vehicle the bushing in to the bore of the component becoming set up (sheave, sprocket, etc.). Be careful when installing these screws. The holes with threads on the bushing are for removal just. Also remember that the looks of a flange on the outside of the bushing doesn’t indicate it’s a QD style. Split Taper bushing also offers a flange, and the two are not interchangeable. The QD design includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers flexible and easy installation while providing exceptional holding power. QD Bushings are used thought out the industry offering comfort and design flexibility. They are precision machined of quality Metal and are installed by tightening many cap screws. This draws the bushing into the taper bore of the product which compresses the bore of the bushing. QD bushings are easily removed by using the cap screws as jack-screws. Dual drilled holes are furnished in QD Bushings permitting mounting of product in the traditional or invert positions. This allows cap screws to be installed through item hub or bushing flange whichever is definitely most convenient. A significant benefit in set up, cap screws are generally inserted from the outside where they are easily accessible. QD Bushings are available from share with all popular bores within the number of each size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping pressure is required over standard bored-to-size bushings. Quick-Disconnect Bushings are essential for installation v-belt drives, synchronous belt drives and roller chain drives.
Our direct supply chain to Martin Sprockets factories gets a wider range of QD Bushings delivered at the proper time at the proper price.
Taper bushing are trusted as well as sprockets, v-belt pulleys, timing pulleys, coupling and other mechanical parts with taper bore connections.
Taper bushing series are constructed with high quality engineered materials with great tolerance. The feature is easy to make use of and needs no additional alteration. These bushings can match almost all types of assemblies and sizes. They are the best choice in style for mechanical connections.
No costly re-boring: complete range of both metric and imperial obtainable.
Standard range matches up to 125mm/5″ shafts & Hub diameter required depends on the application.
Complete short reach range offered, for compact lightweight assemblies & Clean, Compact Design.
Simple installation and removal.
The original sheave and pulley installation system developed to facilitate installation and alternative of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and reverse (flange inboard) installation configurations.

NOTE: Install M thru S bushings in the hub to ensure that the two extra holes in the hub are located as far as possible from the bushing’s noticed cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table on back. Do not use extensions on wrench handles. There should be a gap between your encounter of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grasp and press fit.
